The process of testing [poudriere](https://fossil.etoilebsd.net/poudriere/doc/trunk/doc/index.wiki), a tool for mass-producing binary dports packages, exposed stability issues when repeatedly mounting and unmounting many tmpfs systems on large multicore (48) systems. These issues have been fixed. In addition to stability, several changes were made to improve performance in situations with heavy processor and disk usage.
+### New default compiler
+
+The two base compilers have swapped roles. GCC 4.7, introduced as an alternative compiler with Release 3.2, is now the primary compiler used to build DragonFly. GCC 4.4 remains on the system and still has an important role as the primary DPorts compiler. GCC 4.7 brings [OpenMP](http://http://openmp.org/) (parallel programming) support to DragonFly via libgomp as well as stack smashing protection via libssp, neither of which was supported by GCC 4.4. The newer compiler also offers improved C++ and Objective-C support.

### New USB stack
[USB4BSD](http://www.selasky.org/hans_petter/usb4bsd/) is available this release, though not by default. More USB devices are compatible with DragonFly, and xhci (USB 3.0) users may be able to take full advantage of their newer hardware. Since this is a new feature, it is available in 3.4 but *not* built by default. See the [original announcement](http://lists.dragonflybsd.org/pipermail/users/2012-October/017542.html) for how to do so. This feature was available in DragonFly 3.2 but is still experimental.
